@ejwhite922 There's a couple issues with the batch writer and it doesn't
have to do with exceptions being caught. (1) the QueueFullChecker thread
should not be a daemon thread.... "The Java Virtual Machine exits when the only
threads running are all daemon threads" means that the JVM will exit while
flushing to mongo. (2) It doesn't seem like the secondary indexer (i.e.
geoindexer) is flushed when I close down the sail layer. Can you double check
that?
Also, it seems like the JVM takes a very long time to exit after I call
sailrepository.shutDown(). I think has to do with the BatchWriter as well.
